people per thousand square feet. this density, i think, is very important. it means a couple of things. first, it means that san francisco and other transit-rich locations will win over suburban greenfield sites, where projects are typically parked at three or 3.3 per thousand. because if you build this kind of density on market street, or you build it in san francisco, your employees can get there by bike, by muni, by bart. if you build this in north bay shore, you can't get your employees there to build out this kind of density. we're very much seeing this on the peninsula, where the office buildings that are located close to the caltrain are really distancing themselves from the other buildings on the peninsula in the northern part of the valley that aren't near the train. because that access to transit is so incredibly important.
